Abstract:
A door closer comprises a piston cooperating with a rotating pinion. Upon rotation of the pinion in the door opening direction, the piston moves toward the second end of the housing forcing fluid from a second variable volume chamber through a passage to a first variable volume chamber and compressing a spring assembly for storing energy. The spring assembly urges the piston toward the first end of the housing for forcing fluid from the first variable volume chamber to the second variable volume chamber and rotating the pinion in the door closing direction. A controller controls the position of a valve in the passage based on the sensed angular position of a door and the position of the valve for determining the amount of hydraulic fluid flowing through the valve.
Abstract:
A vent controlling apparatus (10) comprising an actuator (18, 30, 23) adapted to open and close a vent, means for converting energy (16) to provide power for the actuator, and control means (60) operative to control the actuator in response to a wirelessly transmitted control signal. The actuator may be a chain actuator and the means for converting energy may be a solar panel or photovoltaic cell. Wireless transmission by a remote transmitter (51) of one or more control signals may be used to remotely control the operation of the actuator to open or close a vent. A remote transmitter may be adapted to transmit an open or close command without user input to thereby automate the opening and closing operation. Automated operation of the vent may be dependent upon an environmental condition.
Abstract:
A chainwinder for a window having an improved structure allowing the chainwinder to be substantially assembled on the base before the covering is attached to the base, and allowing for adjusting the effective length of the chain without disassembly and improved structures substantially aiding strength of chain.
Abstract:
Provided herein is a curb-mounted skylight having a rigid plastic curb frame, a mechanism for firmly securing the curb frame to an opening in a building, a transparent or translucent covering element, and a mechanism for retaining the covering element on the frame. The curb frame includes a fixed base frame (having an interior frame and a counter-flashing element) and a moveable sash frame (having an accessory shelf and a sash). The base frame and the sash frame may be connected to one another by a first hinge member integral with the counter-flashing element and a cooperative and complementary-shaped second hinge member attached to the sash. The hinge members form a watertight seal and may be disengaged to permit the sash to be removed from the skylight assembly during installation, if so desired. Because the frame and hinge components are made of plastic, the skylight assembly is relatively lightweight.
Abstract:
A guide rail assembly for moving a closure panel of a motor vehicle between an open position and a closed position includes a guide rail fixedly secured to the motor vehicle. A slide mechanism slidably engages the guide rail. A rod has one end coupled to the slide mechanism and an opposing end coupled to the closure panel to move the closure panel as the slide mechanism slides along the guide rail. A drive is fixedly secured to the guide rail for selectively driving the slide mechanism along the guide rail. A clasp is operatively secured to the slide mechanism for selectively coupling the drive to the slide mechanism such that the drive moves the slide mechanism along the guide rail to move the closure panel between the open and closed positions when the slide mechanism is coupled with the drive.
Abstract:
Frame assembly for windows each provided with a frame (4) and a closing member (3) supported by the frame (4) in a freely rotatable manner about at least three hinging axes (22); at least one first body (6) being mounted on the closing member (3) and having an axially symmetrical portion (17), and a second body (5) being mounted integrally on the said frame (4); the said second body (5) having a concave portion (16) housing the said axially symmetrical portion (17) of the said first body (6) in a mating manner and being able to support the said closing member (3) together with the said first body (6); connecting devices (30) which may be selectively actuated being provided in order to couple rotationally the said closing member (3) with the said frame (4) about an axis (22) chosen from at least three hinging axes (22).
Abstract:
An electric operator device (1) for opening and closing a window (2) with pivotal sash (5) and comprising an operator housing (4) designed to be fastened to the frame (3) of the window, preferably to the top member thereof, said operator housing having a built-in drive motor in transmission connection with an operating member (6), which in the closed position of the window is accommodated in the operator housing (4), and a mounting bracket (9) for connecting the operating member (6) with an operating means (7), connected with the sash of the window, preferably the top member thereof. The window (2) can, in the closed position and affected by said operating means (7), be locked by engagement between locking means (11) in connection with the sash (3), preferably the top member thereof, and a strike plate (8) fastened to the frame (5), preferably to the top member thereof. The electric operator device is characterized in that the operator housing (4) comprises a strike plate (8) which is fixedly positioned relative to the frame (3) by means of co-operating positioning means (13, 16, 17) arranged on the frame (3) and the strike plate (8).
Abstract:
The invention pertains to a chain drive for bottom-hinged or top-hinged open-out panels, with an oblong box-type housing (5) that can be attached to the frame (1) and that has three chain-guide sections (12a, 12b, 12c) running parallel to longitudinal side of the housing (5), with connecting sections (13, 14), and that has the requisite power chain drive (15, 15a, 22-26, 29) with drive axes (26, 15a) parallel to the chain-drive sections (12a, 12b, 12c). The chain-drive sections are essentially the length (L) of the housing and the fitting height of the drive motor (22).
